Hello! I'm taking PSLE Science tomorrow too!

Well, here's a list that I can think of right now.

Magnetic Materials:

Iron
Steel
Cobalt
Nickel

My science teacher says we only need to know iron and steel.

Electrical Conductors:

Water
Metals

Heat Conductors:
Metal

Common Electrical Insulators would be plastic and rubber.
Common Electrical Conductors would be iron,steel etc. Water and carbon are also electrical conductors.

Wow, thanks.
And while you're here, i just wanna clear some doubts. Is copper an electrical/heat conductor and/or a magnet? O.O

Oh and, I don't remember where, but i read somewhere that steel isn't a natural magnet, and that it needs to be magnetised.. is that true?

Hello again.xD.

I'm no science expert but as far as I know from my notes, steel is an alloy.
And copper is non magnetic but is an electrical conductor.
It is also a heat conductor.
I got my answers from powerpoint slides done by my class and from the web.[/quote]Thanks.. i'll just remember steel is an alloy although i don't know what an alloy is.
Good luck for tomorrow..
do you mind me asking what school you're from?

Good luck too!

I'm from compassvale primary. How about you? :celebrate:

Mine asks us to remember

SIN.

LOLS. He said that Cobalt wasn't very important.
As long as we knew Iron and Steel its okay.

Hi, i go to opera estate... it's a neighbourhood school and it's ---------------------. you probably haven't heard of it before.... i transferred this year to that school since we moved house.

btw, how do you study your science?

I've heard of Opera Estate. My school is a neighbourhood school too.
Hmm I make notes with reference to guide books, and make powerpoint slides, I read my guide books, listen to teacher, attend optional science classes and do practices.

Since all paper is easy, do u all think the science will be very hard?

[livewith_vanilla]

I’m confused about the different beaks of birds and their uses.

Can someone give me a consolidated list of the various beaks and their uses?

Thanks.
